“Three years after the Gulf was inundated with BP oil, the wildlife, habitats and people of the Gulf are still feeling the effects of the disaster,” [National Wildlife Federation’s David] Muth said. “In 2012 alone, some 6 million pounds of BP oil was collected from Louisiana’s shorelines and 200 miles of coast remain oiled. We can’t allow BP off the hook for anything less than justice requires—a full payment for its recklessness so that real restoration of the Gulf’s ecosystem and economy can begin.”

Yet three years after Tesoro and Deepwater Horizon, both inquiries remain open – exemplars of a chemical board under attack for what critics call its sluggish investigative pace and short attention span. A former board member calls the agency “grossly mismanaged.”

The prospects for bringing large amounts of Canadian heavy crude oil into the United States by train is a contentious issue as the U.S. government weighs whether to allow the controversial Keystone XL pipeline to go ahead.

The Keystone XL pipeline debate comes to a head in Grand Island, Neb., as the State Department holds a public hearing on the Canada-Texas pipeline. If the passionate, opposing sides agree on anything, it's that the Keystone XL pipeline debate is about more than just a pipeline.

U.S. construction workers, environmentalists and company executives squared off on Thursday at a raucous meeting on the Keystone XL oil pipeline, but it was unclear the gathering changed any minds on the controversial project.

Today, citizens will gather at a hearing on the pipeline in Grand Island.
...TransCanada made the mistake of bullying our fiercely independent farmers and ranchers. Landowners say the company threatened to take their land if they didn’t cooperate and warned them that later offers of money would be much smaller if they delayed. TransCanada also insisted, landowners say, that they sign papers agreeing not to talk to the press or anyone about their agreements.

Many Americans assume that the chemicals in their shampoos, detergents and other consumer products have been thoroughly tested and proved to be safe. This assumption is wrong. Unlike pharmaceuticals or pesticides, industrial chemicals do not have to be tested before they are put on the market. Under the law regulating chemicals, producers are only rarely required to provide the federal government with the information necessary to assess safety.

More than half of samples of ground turkey, pork chops and ground beef collected from supermarkets for testing by the federal government contained a bacteria resistant to antibiotics, according to a new report highlighting the findings.

Chevron Corp. helped write the first-in-the-nation rule ordering reduced carbon emissions from cars and trucks...Now Chevron is leading a lobbying and public relations campaign to undercut the California mandate aimed at curbing global warming...

Judging by the reactions of other respected scientists, though, the idea that global warming is off the hook is probably too hasty. While the report did fail to find a climate-change connection, it also failed to identify any other “proximate” — i.e., direct — cause, either, leaving more questions unanswered than answered.

Large PVC pipes led from the fish basins to a "water garden," an area the size of a small bedroom, canopied by huge banana leaves. Growing beneath them were about 10 different plants, including coffee and lemongrass. I would later describe this sight to friends and family as my come-to-Jesus moment.

[T]he electric power sector is facing “disruptive challenges,” a mix of transformative technological and economic changes, as well as regulatory constructs, that could challenge and transform the electric utility industry. The financial risks created by these challenges include declining utility revenues and increasing costs. This is not new. However, what could be new, for some at least, is that these challenges not only affect the utilities and their shareholders, as suggested by Mr. Nelder, but, first and foremost, they also affect their customers.

Despite all the mounting scientific concern, the political rhetoric and the clean technology of the past decade, the growth rate in global carbon emissions has not reduced at all. Why? Because we continue to extract and burn fossil fuels more than ever before...

Based on current pledges, global average temperatures could rise by 3 to 5 degrees Celsius (5.4 to 9.0 degrees Fahrenheit) this century --- way above the two degrees Celsius being targeted, said a UN Environment Programme (UNEP) report.

Top climate scientist James Hansen tells the story of his involvement in the science of and debate over global climate change. In doing so he outlines the overwhelming evidence that change is happening and why that makes him deeply worried about the future.

It's simple: If there is to be any hope of avoiding civilization-threatening climate disruption, the U.S. and other nations must act immediately and aggressively on an unprecedented scale. That means moving to emergency footing. War footing. ...It is unpleasant to talk like this. People don't want to hear it.

"The door is closing," Fatih Birol, chief economist at the International Energy Agency, said. "I am very worried - if we don't change direction now on how we use energy, we will end up beyond what scientists tell us is the minimum [for safety]. The door will be closed forever."
